Tube rolling unit 30-102 with continuous mill 
Exit side of continuous mill

The unit is intended for the production of hot-deformed seamless commercial tubes as well as for boiler tubes, gas-lift tubes etc. from carbon and low-alloy steel grades.


The continuous tube rolling unit ÒÏÀ 30-102 is the most modern and high-capacity device for the production of hot-rolled seamless tubes.


The continuity of process, high rolling speeds, the production of wide rolled stock from rough tube of single diameter, full automation of transporting operations provide the production up to 750000 t/year. The unit has an automatic system for thinning of tube ends in the continuous mill; it permits to decrease the metal wastes at reduction by 30-50%.
